没有UITableViewController的UIRefreshControl不调用选择器 [英] UIRefreshControl without UITableViewController not calling selector
问题描述
我有一个UIViewController,其中有一个UITableView作为子视图。我正在尝试在桌子上添加一个下拉菜单。
I have a UIViewController that has a UITableView as a subview. I am trying to add a pull-to-refresh on the table.
下面是我发现的一些示例和讨论此处,我显示了UIRefresh,但从未调用选择器。我没有收到发生拉动动作的通知。
Following some examples and discussions that I found here, I have the UIRefresh showing but it never calls the selector. I am not getting notified that the pull action happened.
我不能使用UITableViewController作为我的主控制器,因为我需要在屏幕底部添加一个固定按钮。
I cannot use a UITableViewController as my main controller as I need to add a fixed button at the bottom of the screen.
我感觉自己缺少了一些希望对其他人显而易见的东西。
I have the feeling I am missing something out that hopefully is obvious to someone else.
@interface ActivityViewController ()<UITableViewDelegate, UITableViewDataSource, UIScrollViewDelegate>
@end
- (void)viewDidLoad{
[super viewDidLoad];
_myTableView.delegate = self;
_myTableView.dataSource = self;
_tableViewController = [UITableViewController new];
_tableViewController.tableView = _myTableView;
[self addChildViewController:_tableViewController]; // Not sure this is necessary
_refreshControl = [UIRefreshControl new];
[_refreshControl addTarget:self action:@selector(loadMoreData) forControlEvents:UIControlEventValueChanged];
_tableViewController.refreshControl = _refreshControl;
}
- (void)loadMoreData{
NSLog(@"loadMoreData");
}
推荐答案
好的,现在可以了。但是我不确定为什么!我有点离开了,改变了其他需要做的事情,然后昨晚再次测试,它开始工作了。我承认我有点困惑。我使用了以前的帖子此处中给出的答案中的以下代码几天之前。因此,感谢您的时间和投入。
Ok this is now working. But I am not sure why!! I kinda left it for a bit, changed other things that needed doing and then tested once more last night and it was working. I admit I am a bit confused. I used the code below from this answer given in earlier posts here as I did a few days ago. So thank you for the time and input. It works perfect now, as expected.
// Refresh control
UITableViewController *tableViewController = [[UITableViewController alloc] init];
tableViewController.tableView = self.myTableView;
self.refreshControl = [[UIRefreshControl alloc] init];
[self.refreshControl addTarget:self action:@selector(loadMoreData) forControlEvents:UIControlEventValueChanged];
tableViewController.refreshControl = self.refreshControl;
